Geochemical study of water and gas discharging from the deeply incised aquifer system at the Grand Canyon, Arizona, provides a paradigm for understanding complex groundwater mixing phenomena, and Quaternary travertines deposited from cool springs provide a paleohydrologic record of this mixing. Geochemical data show that springs have marked compositional variability: those associated with active travertine accumulations (deeply derived endogenic waters) are more saline, richer in CO2, and…

Degassing of mantle-derived CO2 and He from springs in the southern Colorado Plateau region—Neotectonic connections and implications for groundwater systems
Groundwaters of the southern Colorado Plateau–Arizona Transition Zone region are a heterogeneous mixture of chemically diverse waters including meteoric (epigenic) fluids, karst-aquifer waters, and
Aqueous and isotope geochemistry of mineral springs along the southern margin of the Tibetan plateau: Implications for fluid sources and regional degassing of CO2
Springs issuing from different faults and shear zones along the crest of the Himalayas tap three different levels of crust beneath the Tibetan Plateau. From structurally highest to lowest these are
The La Madera Travertines, Rio Ojo Caliente, northern New Mexico: Investigating the linked system of CO 2 -rich springs and travertines as neotectonic and paleoclimate indicators
The La Madera travertine and CO2-rich spring system of northern New Mexico provides a linked data set to lineament. Water chemistry modeling shows that most of the CO2 is endogenic (derived from deep
Identifying origins of and pathways for spring waters in a semiarid basin using He, Sr, and C isotopes: Cuatrociénegas Basin, Mexico
He, C, and Sr isotopes are used to infer spring sources in a water-stressed area. Spring-water origins and pathways in the Cuatrocienegas Basin are revealed by linking structure and geochemistry via
Tufa and travertines of southern Italy: deep‐seated, fault‐related CO2 as the key control in precipitation
Continental carbonates of Quaternary age in southern Italy commonly exhibit the facies of calcareous tufa, often reported as related to shallow aquifers fed by meteoric waters and to organic
Importance of groundwater in propagating downward integration of the 6–5 Ma Colorado River system: Geochemistry of springs, travertines, and lacustrine carbonates of the Grand Canyon region over the past 12 Ma
We applied multiple geochemical tracers ( 87 Sr/ 86 Sr, [Sr], δ 13 C, and δ 18 O) to waters and carbonates of the lower Colorado River system to evaluate its paleohydrology over the past 12 Ma.
Tectonic control on travertine and calcareous tufa deposition in a low-temperature geothermal system (Sarteano, Central Italy)
This paper presents an integrated study directed toward an understanding of the tectonic control on the hydrothermal circulation and resulting deposition of Middle–Late Pleistocene travertine in a


Variability of karstic permeability between unconfined and confined aquifers, Grand Canyon region, Arizona
Most of the ground water in the Grand Canyon region circulates to springs in the canyon through the thick, deeply buried, karstified Cambrian-Mississippian carbonate section. These rocks are
Isotopic geochemistry of the Saratoga springs: Implications for the origin of solutes and source of carbon dioxide
We report the results of an isotopic study designed to determine the source of solutes and carbon dioxide in the famed Saratoga Springs (New York) mineral waters. These waters have thousands of
300-Myr-old magmatic CO2 in natural gas reservoirs of the west Texas Permian basin
It is shown that Rayleigh fractionation caused by partial degassing of a magma body can explain the CO2/ 3He ratios and δ13C(CO2) values observed in CO2-rich natural gases in the west Texas Val Verde basin and also the mantle 3He/22Ne ratios observed in other basin systems.
